S IEECIFICATION-fQrming part of Letters Patent No. 284,214, dated September 4, 1883,

Application filed JanuarySL1883. (No man.)

To all whom it may concern/.-

Be it known that I, FRANK J. LARKIN, a citizen of the United States of America, re-

siding at Chicago, in the county of Cook and State of Illinois, have invented an Improvement in Wagon-Springs, of whichthe following is a specification, to wit:

tion applied to a side-barframe.

This invention relates to an'improvement in side-bar vehicles; and it consists in the combination of the u'sualside-bar frame, with cross-blocks supported upon bars or springs hinged in the center and acting upon coiled springs secured in hangers from the under 1 sides of the bed-blocks and side bars, substan- I 5 tially as willbe hereinafter more fully set forth. In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which Figure 1 is a perspective view of my inven- Fig. 2 is an end elevation of the same; Fig. 3, a cross-section through one of the supporting-bars and hangers; Fig. 4, a detailed perspective view of one of the spring-hangers. Figs. 5 and 6 are perspective views of reverse sides of the bearing-plate, and Fig. 7 a similar view of one of the small journal-blocks applied to this plate. I I

A represents the axles of avehicle, upon I which the side bars, BB, are supported in the clips 0 0,.each providedwith a small pin, 0

usual or any desired manner.

0 0 represent the cross-blocks which sup port the bed of the vehicle between the side springs, E, in a hanger, F, depending from 45 the side bars, B B. The plates E are provided with one or more circular recesses or sockets, at, on the under side, in which the ends of the coiled springs E are socketed; and the upperside is formed with a, longitudinal recess, c,'in which is journaled a small friction-roller, 0, upon which the spring-bar D rests and slides. The plates E on either end are also provided with small castings E secured on their upper side, in which is journaled a second roller, 6', which rests upon the upperside of the'spring-bar D; and thehangers- F are provided with two vertical guide-rods, If

f, secured in the hanger at their lower ends,

andat the upper in a plate fixed to the side bar. These rods pass through holes in the plates E and serve to guide them in their vertical movement. 0 O are are also furnished with hangers F,

provided with a plate, G, resting upon the The outer ends of the blocks they turn easily upon their pivot-pin in the clips c c, and the outer ends then slide outward between the rollers in hangers, and the weight acts to compress the springs G upward and the springs E downward, as will be readiy seen by reference to the drawings.

Any desired number ,of springs E G may be used in the hangers, and are evenly compressed by the plates E G, while the frictionrollers allow the spring-bars D D to play freely back and forth. To prevent the rattling usual when such rollers are used and enable me to fit them closer to the bars D, I construot these friction-rollers of rubber.

It is obvious that the bars D may be made rigid, if desired; but when formed of spring metal they add an' additional spring to that of the coils E G.

The device is strong and economical of construction, very easy in motion, and does not produce any unpleasant rattling.

Having thus fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. In a sidebar vehicle, the plate E, provided with two rubber rollers, between which the spring-bar D has a free endwi'se play, in combination with the guide-rods f f, spring or springs E, and hanger F, secured to the frame, substantially as and for the purpose set forth.

2. In a sidebar vehicle, the two springbars D D, hinged to a clip in the center oi the crossblock 0 G, in combination with the hangers F, depending from the ends of the cross-blocks,

.and provided with guide-rods f f, plate G,

having rollers g g, between which the springbar passes, and springs G, adapted to be compressed upward, and asimilar hanger, F, upon the side bar, provided with plate E, springs E,

guides f f, and rollers a 0, between which the outer ends of the bars D play, substantially as and for the purpose set'forth.

3. In a side-bar vehicle, aplate, E, recessed upon one side for the socketing of the springs E and upon the other for the journaling of a rubber roller, 6, and provided with blocks grooved to form journals for a similar rubber roller, 6, in combination with the hangerF, supporting-springs E, and guide rods ff, whereby the ends of the spring-bars are given both a vertical and an endwise motion, but

held firmly against rattling, substantially as I shown and described.

4. A side-bar vehicle consisting, essentially, of the axles A, side bars, B, cross-blocks G,

transverse spring-bars D, hinged at their in-
